Specification of Letters Patent.

Be it known that I, Hanvnr S. Finnsronn, 'a citizen of theA United States," residing at Akron, in the county ofy Summit and State of Ohio, have invented certain `new and useful Improvements .in Side-Tire Tires, of which thefollowing is a specification.

, Myvinvention relates to side wire tires4 and refers particularly to the shape ko f side wires andthe cross rods coperating therev v with".V j

, I ani aware that in order to'ietain a tire within Vits l metal tire rim, side wires have heretofore been' used `inveonnection with cross rods, but bot'hthe side vwires and'the cross rods have been inaderound in cross -sectio'nL As a -result the contacts between `\the side wires and cross 'rods have theoreti- *cally been mere points and in order topre- 'vent the side .wires from rolling laterally from the tire rim,`it has been necessary to make the flanges on said rims ofconsiderable height.- In `,constructions of this kind,

` too, there is a .tendency forthe 'side wire and crossV rod. to r-ub on one- `another and wear away, particularly when the surfaces 'of contact ai'e relatively small.

It is the object of my invention to avoid i Y all ofthese-diiiculties'by making both the cross rods and the'side wiresfwith flatcontacting surfaces thereon with the result that- 'considerablc' contacting 'surfaces are obtained lieti'veen` .each of theucross rods andthe-side 'wires which engage said rods.

.In this 'wav the tendency of; the side wires to become displaced laterally is avoided and it is thus possible to make the anges of the tire -rim considerably lowerthan was forsurfaces.

inerly the case. ,'Also, the wear between the side'wires' ander'oss rods is considerably reduced because of the .increased contacting These and other vadvantages of in'y invention will beni-ore readily understood by reference to .th accor.' panying drawings which represent a. preferred form I, of my improvement, and in`whieh Figure lis a perspective and partly transverse sectionalview showinga portion of a tire held in position within the tire rim by means of the cooperating actioiiof the cross rods and side wires, this rim'v also 'being shown as held in position on the'felly 'of the wheel. Fig. 2 is a perspe'ctiveof one of the cross rods. l y

The tire rim 5, having the outwardly extending fianges 6,'"is held in position on` the felly rim 7 in any suitable manner. Pass. ingthrough the tire'S-iis a plurality of cross rods 9, each of which is engaged on its ends by the side wires 10, which preferably occupy posit-ions'in the grooves 11 in the sides of. the tire 8. .Each rof the cross rods 9 has vPatentedApr. 8,1913.-

Application filed January 30,1911. Serial No. 605,526. i

a fiat upper surface 12 which is engaged'by a corresponding surface 13 on the bottom of each of the side' wires 10. It will be apparent that theside wires' 10 are located justv inside of the flangest., and, on accountof the engagement of the fiat surfaces 12- .of the cross rods 9 by the fiat surfaces 13 of the side wires 10,ithe tendency of the side wires to roll outwardly in a lateral direction is counteracted, and' itis necessary to make the iianges 6 of a height only approxi- .mately equal to the upper or outer portions of the pei'ipheries of said side wires. This is apoint;- of great advantage inasmuch as the edges of the lai'iges G on the lower side of the wheel. thus yoccupy, .positions much farther removedl from-.the ground than is the case in the' old construction.`

It .is well'understood thatin constructions of-tliis kind there is a 'tendency for' thev tire immediately in front of itsfpointof contactv with the ground to 4crowd forwardly, and. that after that lp 'artof the tire passes the pointrof contact with thegroiind the rubber has a chance to react and readjust i itself, the result beingthat the cross rods and side' wires riib'upon each other. The prevent-ion of .all but a minimum of wear of these parts tlirough the 'large contacting areas provided is an important feature of this invention.

It will be apparent to those skilled in the art thatconsiderable change could' be made Vin `the .detailed vconstructior` of'the parts which' Iwhave described without departing from' the spirit or' scope o f my invention.

What I claim is: l

The combination of a tire rim` a resilient. tire thereon, and means for reinforcing and fastening the t-ire on the rim comprising a plurality `of lrods passing transversely through the base portion ofthe tire, said rods bein rounded for the major portion thereof includingA their under surfaces 1 per surface of eaclr rod being flattened to prevent turning of 'the rod in, the tire, and.

which are disposed towardthe rim, the up- .the ends of the rods projecting outwardly beyond the opposite edges 0f tliedbasepolftion of 'die tire to constitutefexpo'sed lippen fiat bearing surfaces, and v retaining rings' passingbr around the op'p'osit'e sides of v'che it-ire each having the major portion thereof rounded including Viis inner surface' which' is disposed-towardthe tire, 'and-*its *under surface being continuously Het `tolbear .directly upon the `Correspondingnfljy fiat ex-v i 10 tended upper bearing surfaces of the transti'ie --beiweensaid transverse'rods*4 and the tire-'rim While permitting a f ree slidable re- Y v*lation to existbefcween the retaining rings :rnd-trnsverse rods both circumferentialiy 'and transverseiyof the rim.vr
